Starting right off, that bass sound makes it sound like this is just playing back on an actual DS. Actually, the whole song is like that, which usually doesn't fly for OCRs. Your drums sound like they're interesting, but they are really hard to hear over the synths. By 3:00 I feel like I've heard the same thing over and over; the song has no dynamics. It's just in your face pounding the whole time, and not in a good way. Your actual synths weren't too bad- you definitely have promise. Practice your drums / beats / percussion and this will come out a lot better. Definitely keep posting your material!
